fix(migrations): skip existing columns and indexes on databases migrated elsewhere

Browse Source 
On a database NexusDashboard (or a server's own changes) already migrated, 29, 30 and 40 logged
an error for every column that was already there, and 40 and 57 added a second index on
columns MariaDB had already indexed for the inline REFERENCES foreign keys of 0_initial.sql.
Add those columns and indexes only when information_schema says they are missing.

40 also gives pet_names.owner_id values written before 23_store_character_id_as_objectid.sql
the persistent bit, as 23 did for every other character id column, so they match characters.
